How to adjust the temperature of pig raising in winter?
2020-12-18
Temperature is extremely closely related to the growth and health of pigs. Therefore, in the feeding and management of pigs, paying attention to the management and adjustment of temperature and creating a suitable growth temperature for them is a necessary guarantee for promoting their rapid growth or fattening and obtaining higher economic benefits.
Ambient temperature
When the outside temperature is too low, in order to maintain a normal body temperature, the pig's body must enhance the oxidation and decomposition of substances in the body to generate heat energy to supplement the loss of body heat. Generally speaking, when the temperature around the piglet is 20℃~26℃, the metabolic consumption is low and the growth and development are normal. However, large pigs have lower metabolic consumption at 15°C to 20°C and normal fat gain. Therefore, it is necessary to pay attention to the cold-proof and heat preservation work of the pig house (such as covering the pig house with plastic film, etc.) and increase the temperature in the house, which can not only reduce the consumption of pig body metabolism, but also promote its growth and development and increase fat.
Drinking water and food temperature
The temperature of drinking water and food for pigs in winter is also closely related to the growth and health of pigs. A lactating sow needs about 17.5-22.5 kg of water and food per day. If the water and food temperature is 0℃, the water and food temperature must be raised to the level of 39℃, and the pig’s body will consume 682~878 thousand. The caloric energy of the card is equivalent to the need for 0.5 to 0.75 kilograms of concentrate per day to be used in vain to maintain body temperature, and cannot be used for lactation, growth, and fat gain. Therefore, when feeding pigs in winter, they should always feed warm food and warm water, which can reduce feed consumption and improve feeding efficiency.
